This invention relates to a. comhination dovetaii and door bumper.4 it has heen proposed heretofore to combine the humper and the registering device in e. single unit so that when the door is swung into closed posin tion it willi he properly aligned in the door opening and when the latch is releesed, it will loe thrown open. This proposed amen. e ment works on the theory that it is desire le to hold the door rigidly egeinst u and down vibration. The diculty with this proposed. type of combination dovetail end bumper is that hoiding the door rigidly against up sind down vihretion transfers the stress to the hinges whichl acceleretes the weer et' the hinge pins and consequently rettles soon te sult. e

It is en object ci this invention to overcome this diculty and yet achieve the desirehle functions of properly aligning the door in the door opening and of throwing the door open when the latch has heen released, and at the same time not transfer excessive stresses set up by the loody weave to the hinge pintles.- This has been achieved by permittinga cushioned up and down vibration of the door.

It is a further object of this invention to produce a combination dovetail and bumper which will properly register the door in the door opening and throw the same open upon the release of the latch and which at the same time will cushion up and down vibration of the door in the door opening.; j Y

It is an object of thisinvention to produce a combination dovetail and bumper havin wedge sindl socket members which permitan yieldably resist relative movement between the door and the door opening in a plane normal to that of the door.

It is-an object of this invention to produce -a combination dovetail and bumper having-a spring loaded socket member movable 1n wardly and outwardly which is. resiliently cushioned for up and down movement and in which the resilient cushions are so mounted that they are not subjected to sliding displacement. Y lt is an object of this invention to produce a combination dovetail and bumper in which the socket member is yieidehly movable inwerdiy and outwerdiy and upwerdly and downwerdly end in which the yieidahle means for permittin j upwerd end downward movement ot the soc et ere errenged to move inwardly and outwardly with the socket me ln the drewin: Fig. i is a pien view of a comhinetion done teil and bumper..

Referring more particularly to the draw--v ingsfthe combination dovetail and 'bumper comprises an outer cover plate 1 having an L shaped flange 2 which is adapted to be secured either to the body or door pillar. The cover plate has riveted or otherwise secured thereto the socket housing 3. The housing 3 comprises the side walls 4, the' rear wall 5 and the bottom 6. The front of the housing Sis closed by the L shaped flange 2 of the cover plate. The socket member 6 is sho/wn in detail (Figs. 7, 8, and 9) and in this instance isa die-casting. The socket member d is provided' with a wedge shaped socket 7 and' a pair of spring receiving openings 8, one on each side of the socket 7. The socket member 6 is likewise` provided on each side with a air of reduced projections 9 each ofl whi 100 cup 10.

adaptedv to slidably e engage the inside of a Since the socket member 6 is adapted to be received by the housing 3 and permit upward and downward movement as well as transverse movement of the door in the door open# ing, to this end the cups each have mount.

ed therein any suitable resilient material such as the blocks of rubber 11. After each cup 10 is provided with the ruber block 11, the open end of the cup is slipped over a reduced projection 9 and then the socket member 6 and associated rubber blocks and cups l0 are `placed within the housing 3 with the bottoms 13 of the cups 10 in sliding engagement with the side walls 4 of the housing 3. Since the projections 9 slidably engage the inside of the.

cups 10, therefore the socket 6 is free to move upwardly and downwardly relative to the body pillar or right and left as viewed in Fig.

3 wlthin the housing 3 and will be resiliently I.

' than between the rubber and the socket member or the casing 3.

Suitable coil springs 14 are positioned in the openings 8 and are backed up by the rear l wall 5 of the housing 3.

ycs

As shown in Figure 1, the cover plate 1 is provided with a suitable opening 15 which permits the engagement of the wedge memr 16 in the socket 7. The sides `of the socket 7 and of the -wedge member 16 are correspondingly formed so that the wedge will not f stick in the socket 7. As is the usual practice, the wedge member 16 is mounted upon the door pillar and the socket member is mounted uponr the body pillar or .these positions can be reversed.

In operation it is evidentl that when lthe` door is swung to closed position the wedge 16 will engage 1n the socket 7 and the Haring sides o the wedge will cooperate withY the corresponding sides of the socket to properly align the door in the door opening. At the same time the socket member 6 will be pushed inwardly and the springs 14 compressed.

.So long as the door is latched the door will be permitted to move upwardly and downwardly in the door opening and be resiliently cushioned by the rubber blocks 11 since the reduced projections 9 of the socket member 6 move inwardly and outwardly in the cups 10. At the same time inward and outward movement of the socket 7 and associated rubber blocks in the casing 3 is permitted by virtue of the sliding frictional contact between the bases 13 of the cups and the side walls 4.0i the socket casing. Whenever the latch bolt is released, the loaded coil springs 14 immediately expand to thrust the door outwardl Since, as stated above, the flare of the si es ,of the socket 7 and the wedge 16V is such thatsthe wedge lwill not stick in the socket 7, it is evident that the socket16 is free to move in and out and up and down in vcushioned by either or both the coil springs 14 and the rubber blocks 11 and hencepermits the vehicle body to weave without throwing undue strains and stresses upon the door hinges. A t the same time it will be noted the rubber blocks 11 perform their cushioningfuntion free from sliding frictional engafrement with the housin socket 6. referably the rubber locks 11 are loaded when in assembled position within the housing 3. It will be noted that the socket is self-aligning within normal requirements. If the wedge andsocket dol not seat perfectly due to variations in installations .the' socket will twist edgewise against the rubber blocks and the springs, and thus eHect a perfect seat between the wedge and the socket. A small commercial clearance is allowed between the projections 9 of the socket and the cups 10 to prevent binding when the socket member is slightly cocked to effect a perfect seat between the socket and the'wedge. l 4

In the modified form of the combined dovetail and bumper the wedge member comprises a mounting plate 20 provided with the upstanding lug 21". A block of rubber 22 is molded so that it may be assembled about the upstanding lu 21. This block'of rubber has aperipheral ange 23. A hollow wedge member 24 is then pressed over the rubber block 22so that the rubber is loaded and with its lower edge cushioned by the rubber flan e 23.

T e socket member comprises the two shoe members 25 and 26 which c-an be made of any suitable material, such as bakelite. These shoe members are adapted to' be received within the socket housing 27. The socket housing 27 is provided with the end walls 28 which have a sliding engagement with the sides 29 of the shoes 25 and 26. Each shoe v25 and 26 is provided with a kerf 30 for the reception of the return bent portions 31 of the housing 27 The return bent portions 31 have a loose `iit in the kerfs 30. The Shoe 25 is provided with a wedge shaped projection 32 which engages in the wedge shaped recess 33 of the member 26 to provide a pivotal engagement between the two shoe members. The shoes likewise areprovided with the openings 34 for the coil springs 35. The'.

ne normal to the doory 3 orI the rooy flare of the corresponding sides 36 and 37` Lacasse of the socket and wedge members respectively v is such that the wedge will not stick in the 'rubber block 22 upon which thewedge 24 is oated permits up and down movement of the door in the door opening, and the spring 35 permits inward and outward movement of the socket members. The socket members and 26 are arranged primarily for inward and 'outward movement although by virtue of the loose lit of the return bent portion 31 in the kerfs and the pivotal connection 32 and 33 between the shoe members, a limited spreading is permitted between the two shoes.

lnthis form ci the combination dovetail and 33, there is no chance for the dovetail to lock l the door in disaligned relation with the door opening in case the door is closed while the door opening is temporarily out oit positionor distorted as is often caused by one Wheel be'- ing somewhat lower than the others when the car is parked. lf 'the door is closed while the.

door openin is 'somewhat distorted, the wedge 2li wil engage in the socket 36 and force the same inwardly compressing the coil springs 35 but both of the socket members 25 and 26 will move inwardly together and es soon as the car is set in motion and the wheels are again placed on the same level, the wedgewill attain a perfect seat inthe pocket and hence properly align the door in the door opening.
